Hello,

I am also trying to use an external debug probe with the F28069 experimenter kit.

I was reading Brett Larimore's comment:

"I would recommend populating J8 with a jumper if you use an external emulator with the docking station (Docking-Stn USB-EMU [R3]).  This will hold the on-board emulator in reset and will keep CCS from being confused about which emulator it should be trying to use."

I cannot find J8 on the same docking station. Can someone point it out to me? 

Thanks

    Ki,

    It's near the edge of the board, on the side opposite of the 5V input.

    Thanks! I put the jumper there but I still have issues connecting using my XDS110 debug probe.

    I was reading CC2806x-InfoSheet_Rev0.4_20Jan2014.pdf and saw the below comment under Section 2:

    "This controlCARD is designed to be debugged via the on-card emulator. JTAG ports on the docking station or any other baseboard will not be able to connect to the MCU."

    Based on this, I must use the integrated XDS100v1?

    Thanks

    Ki,

    It depends on the controlCARD variant that you have. There is an ISO variant where the JTAG signals are only routed to an isolated, on-board XDS100 via a USB-mini connector. There is a non-ISO variant where the JTAG signals are routed through to the docking station.

    You will most likely have the ISO variant if you see a USB-mini connector on the controlCARD.

    Ah, that is it. I have the ISO version. Thanks for clearing that up!
